Biology

Mudkip is a small amphibious quadruped Pokémon. It has a blue body with a light-blue underside. It has a large head with a blue fin on top, and a light-blue tail fin. It has black, beady eyes and orange, star-shaped gills on its cheeks. By using the fin on its head, Mudkip is able to detect changes in air and water currents as well as bodies of water. Its fin can also point in a certain direction, as seen in the anime. Mudkip is capable of moving or crushing boulders larger than itself. Its large tail fin propels it through water with powerful acceleration.

According to its Pokémon Ranger browser entry, Mudkip is a very docile Pokémon. Mudkip lives in swamps and other wetlands, where it sleeps by burying itself in soil at the water’s edge.

In the manga

In the Pokémon Adventures manga

In Pokémon Adventures, when Ruby was attacked by Sapphire's Torchic, Professor Birch told him to look in his briefcase, to pick up the Poké Ball with a blue Pokémon and to throw it. The Poké Ball released a Mudkip and he nicknamed it Mumu. At the beginning, Ruby was disappointed with it because it wasn't as attractive as his other Pokémon and it couldn't participate in any Pokémon Contest. He tried with different conditions and then decided that Tough Contests would be perfect for it. Mumu eventually evolved into a Marshtomp and then into a Swampert.
